Equilibrium Question 547

Question: For the reaction $ PCl_3(g)+Cl_2(g) $ ⇌ $ PCl_5(g) $ at $ 250^{o}C $ , the value of $ K_{c} $ is 26, then the value of $ K_{p} $ on the same temperature will be [MNR 1990; MP PET 2001]

Options:

A) 0.61

B) 0.57

C) 0.83

D) 0.46

Show Answer

Answer:

Correct Answer: A

Solution:

$ K_{p}=K_{c}{{(RT)}^{\Delta n}} $

$ =26,{{(0.0821\times 523)}^{-1}}=0.61 $ . $ \Delta n_{g}=1-2=-1 $
